"Reset" cue

I have a number of cues that mess with the selected zones and the top menu buttons using Pangoscript, and I want to create a button that resets them all to the default (in particular that pesky "use cue preferred zones" button which I always forget about). I used to be able to create a script-only cue but I can't do that now? How to do this? (I'd prefer not to do the "universe" to create a control, I want it in my cue grid).
